Hello, this is my first time posting a question, I hope someone can help me sort out my duck injury issue!
I have two female Muscovy ducks, they seem to get along pretty well and I've never seen them be aggressive towards each other. This morning when I went to let the ducks out the one had pretty bad wounds to her face, both sides, just under the eyes. (I attached some photos) I can't figure out what caused such nasty wounds. It has happened once before, last time I put some cream on and separated the ducks for a week until it healed. But I would like to find out what's causing the issue. there is no signs of anything getting into the pen. There are also no other marks or cuts on the ducks body. I do see the other duck try to pick at the wounds, but I am not sure if it is out of aggression or just curiosity. If anyone has any ideas that would be greatly appreciated!
Thanks!
